Two years ago. In the harsh cold of winter, 11 members trained hard for their debut. At first, none of them were delicate and timid, and were in no position to appear in front of an audience. And then, three cherry blossom seasons passed. The 11 members had grown so much that they could carry Sakurazaka on their shoulders. There were many farewells in between, but that only made them stronger and moroe resilient. In the midst of all this, nine fourth-generation members who had passed the auditions joined the group. The first day of the anual training camp. At the previous training camp for the third-generation members, the assigned song was "BAN", which was focused on improving their technical skills. Perhaps because of this, the members gathereed in the gymnasium and were a little nervous before the assigned song was announced. However, the song that was told to the fourth-generation members was a song they had never imagined. What was the intention behind this?

The group splits into three and the lesson begins. As they fumble their way through the choreography, the teacher warns them of their passive attitude towards the task. Then, an incident occurs that shows just how difficult the assigned song, "Seijaku no Bouryoku", is. Normally, dance involves using melody and counting to keep the rhythm. However, "Seijaku no Bouryoku" requires a different approach to distinguish the sounds. The members, who have dance experience, are unable to do this and are troubled and distressed. On the other hand, some members who have no experience begin to stand out. Sakurazaka's performance is not possible with dance skills alone. From the first day, they once again witness the difficulty of Sakurazaka's performance.

"Interpret the lyrics in your own way and share them with your team members." The teacher gave them a task to understand the choreography deeply and to improve its resolution. This steadily starts to produce results in your performance. The members themselves realize this chang, and by the third day of the camp, a slightly more positive atmosphere has emerged. That night, the members decide on the dinner menu and cook for everyone, including the staff. Realizing the importance of eating together in a group setting, the camp finally enters the second half.

The fourth day of the training camp. When it comes to learning dance skills, why are they practicing "Seijaku no Bouryoku" now, which is by no means optimal? And what will the fourth-generation members show, and how do they want to be in this group? The night before the results of the training camp are checked, teacher Takahiro asks the members again. Because they have no dancing experience, they each think about and practice what is important before learning skills, and the essence of this training camp gradually begins to emerge.

The fifth day of the training camp. The day has come to check the results. What thoughts will each member have as they perform? The, the stage moves to Tokyo for the announcement of the results with all nine members in formation, and the story moves further ahead. There is only a little time left until the First Showcase.
